Oh I'm applying them correctly Art. Once you get used to using them they sort of become 2nd nature.

I'd advise you to put some time into learning how to do it yourself. The book "Guide to the National Electrical Code, 2005 Edition" by Thomas L. Harmon is a good book to learn from. Has numerous examples in it. Enough repetitions to get the hang of it. It's the book I've learned the most from:

By the way if you take a Unisaw for example, 3 HP, 230 Volt. If you installed the tool in a residential garage, a commercial warehouse, or an industrial plant the components of the branch circuit would all be sized exactly the same way. No difference based on the type of structure the tool is located in.

Good night creekers.
